Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-30B
The AirTAC Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-30B is a genuine double-acting COMPACT cylinder (Ø32mm bore) whose extend end-position is set by an external M10×1.25 adjustment screw. You can dial the stroke anywhere from 55 to 85 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-30B
The AirTAC SDAJ32X85-30B is a compact double-acting single-rod cylinder featuring an external extend stop. A built-in M10x1.25 adjustment screw lets you dial the outward travel anywhere between 55 and 85 mm directly at the machine, eliminating the need for shims or part swaps. Because the mechanism only limits the endpoint, output force remains identical to a standard 32 mm bore SDA, delivering 402.1 N of push at 0.5 MPa.
This variant utilizes a male M10x1.25 piston rod thread and a PT1/8 air port. Its short riveted body significantly reduces axial mounting depth where a larger profile cylinder would fail to fit. End-of-stroke energy is managed solely by a fixed NBR bumper, which decelerates the piston rather than acting as an adjustable air cushion or a mid-stroke lock.

| Acting type | Double acting |
|---|---|
| Rod end thread | M6×1.0 F / M10×1.25 male (B) |
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 500 mm/s |
| Cushion | Fixed NBR bumper (both ends) |
The adjustment screw shortens the extend stroke by up to 30 mm. Force is unchanged from a standard SDA of the same bore. Specifications follow the official AirTAC SDAJ datasheet.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 kgf | |
Force matches a standard SDA of the same bore; the adjuster only sets the stop position, not the area. Actual usable force is lower than theoretical due to friction.

Where the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-30B Is Used
Machining Clamp Depth
Dial the extend stop from 55 to 85 mm to set exact clamping depth on raw castings of varying widths without reprogramming the PLC or changing fixture stops.
Changeover Dialing
Speed up product changeovers on a packaging line by turning the external screw to shift the 402.1 N push endpoint, accommodating different carton sizes rapidly.
Trial Positioning
Find the optimal ejection point during prototype testing by adjusting the outward stroke on the fly, safely decelerating the tooling via the fixed NBR bumper.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-30B the Right Cylinder?
When sizing this unit, consider the neighboring bores: stepping down to an SDAJ25 yields 245.4 N of push at 0.5 MPa, while stepping up to an SDAJ40 provides 628.3 N. This 32 mm bore generates 402.1 N at 0.5 MPa, translating to a safe working load of roughly 241 N or a vertical lift capacity of about 20.5 kg with a 2:1 safety margin. Choose this specific model if your fixture requires precise on-site stroke tuning across a 55 to 85 mm window.
Confirm the 32 mm bore, 85 mm maximum stroke, 30 mm adjustability, PT1/8 port, and the male M10x1.25 rod thread for your mounting interface. Note that this SKU lacks a piston magnet, so it cannot accept reed or electronic switches. Furthermore, a standard compact cylinder does not hold position upon air loss; the fixed bumper only decelerates near the end of travel. For suspended or vertical loads, integrate an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 55–85 mm
- ✓ Force at your working pressure
- ✓ Access to reach the R adjuster
- ✓ Magnet (S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Lock the M10×1.25 adjuster after setting the stroke.
- check Avoid side load on the piston rod.
- check Front/rear covers are riveted — do not dismantle.
- check Installation by qualified personnel per AirTAC docs.
Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-30B FAQ
At 0.5 MPa it provides 402.1 N of push and 345.6 N of pull. At 0.7 MPa the push is 563 N and the pull is 483.8 N. The theoretical maximum push is 82 kgf at 1.0 MPa.
The M10x1.25 adjuster screw mechanically limits the extend endpoint, shortening the stroke from 85 mm down to 55 mm. It sets the stop position without altering the output force, and it does not lock the piston mid-stroke.
